Lille president Michel Seydoux has criticised Florian Thauvin's agent for "destabilising" the player - but is "99.9 per cent" confident the sought-after midfielder will not leave this summer.

Reports have suggested Thauvin was refusing to train with Rene Girard's team as he continues to be linked with a move to Marseille.

Seydoux, though, told L'Equipe: "It's going fine. His return has been set for tomorrow, Tuesday. He has not said anything to me and I can't be sure the threat came from him.

"I was ready for (the speculation). I knew very well that the matter is only resolved once the transfer window closes.

"I know how the job works, things do not happen with a wave of a magic wand. There is destabilisation, for sure.

"Again, I don't think it is the fault of Florian. He has been led by someone, his agents."

Thauvin signed from Bastia in January and was loaned back to the Corsican club for the remainder of the season.

Asked if he was resigned to losing the player without seeing him make a single appearance for Lille, Seydoux said: "No, not at all.

"I don't have a crystal ball but unless there is an unbelievable offer - and I can't see why there would be because clubs have to be sensible - Florian will be a Lille player, 99.9 per cent. Let me leave 0.1 per cent open."
